Wine may help breast cancer patients receiving radiation

Despite advances in screening and early diagnosis of breast cancer, little has changed in how it is treated over the past ten or twenty years. For most women, it comes down to a choice of mastectomy or removal of the tumor (lumpectomy) and radiation. If it has spread, then chemotherapy is recommended. The good news for women choosing mastectomy is that breast reconstruction techniques have improved substantially, but for patients opting for “breast conserving therapy” an ordeal of several weeks of radiation treatment is still standard treatment. And despite the fact that the breast is conserved, the radiation causes irreversible changes and even some disfigurement on top of the dent left after the lumpectomy. But now there is some evidence that wine may help prevent some of these changes, despite lingering controversy about the role of alcohol in breast cancer risk.


The data comes from a study from the Catholic University in Campobasso, Italy, a center where wine and health research has been particularly fruitful in recent years. The researchers assessed skin toxicity (redness, irritation) from radiation in each of 3 groups of women receiving different treatment doses. Overall, women who drank wine had a lower incidence of skin toxicity compared to nondrinkers (22% vs. 38%), and the amount of daily drinking had an influence as well. Women who drank a half a glass or less had a 32% incidence, while only14% of those consuming a glass a day experience significant skin irritation. However, the percentage increased as drinking increased above a glass a day, with 2 glasses about as high as none. Those who are familiar with my book Age Gets Better with Wine will recognize this as a J-shaped curve, where moderate drinkers enjoy benefits not associated with abstinence or heavy drinking.

Earlier reports on various types of cancer have revealed that polyphenol molecules in wine, including but not limited to resveratrol, have the effect of protecting cells from the toxic effects of radiation while simultaneously sensitizing cancer cell to it. That would provide an explanation to the findings of this clinical study. What isn’t known, and cannot be directly inferred from this type of study is whether supplements of wine-derived compounds will have the same effect. Clinical trials should provide the answers within the next few years.

Wear red and DRINK red for women’s heart health

This Friday Feb 2nd is the annual “wear red” day in Canada and the U.S. to raise awareness for women’s heart health. Why only a day for the number one threat to women’s health? Women are 5 times more likely to succumb to heart disease than breast cancer, which gets a whole month (October.) Another contradiction is that the advice women hear about prevention of breast cancer is the opposite of what you can do to lower the risk of heart disease: a daily glass of wine. Even one drink a day raises your risk of breast cancer, we are told, ignoring the overriding benefits of wine on heart health. Drink red wine to live longer Here’s why I think women should also “drink red.” For starters, wine helps de-stress and celebrates life. Stress is a factor in heart disease, and if that were the only way wine helped it would be worth considering. But the medical evidence is also strong: a daily glass of red wine helps raise the HDL “good cholesterol” levels, which lowers the risk of cardiovascular p…

Which types of wine are the healthiest?

I am often asked after lecturing on the healthful properties of wine which type is best to drink. Since much of the discussion has to do with the polyphenol antioxidants from the skins and seeds of the grape, red wine is the first criterion since it is fermented with the whole grape rather than the pressed juice. This allows for extraction and concentration of these compounds, familiar ones being resveratrol and tannins. But beyond that, which varietals have the highest concentrations?


According to the Roman philosopher Pliny the Elder, “The best kind of wine is that which is pleasant to him that drinks it” but modern science expects more specifics. (The point of course is that if you have a wine that you enjoy you are more likely to drink regularly and therefore reap the benefits.) But there are several difficulties in singling out certain wines for their healthful properties. Which compounds to measure? Are we talking about heart health or the whole gamut? Is it the varietal of the …

The J-curve is dead. Long live the J-curve!

There is a resurgence of debate about the validity of the J-curve, especially as it relates to alcohol and cancer. A 2014 report determined that “alcohol use was positively associated with overall mortality, alcohol-related cancers, and violent death and injuries, but marginally to CVD/CHD” (cardiovascular disease). In other words, there was little benefit if any in terms of heart disease but a big upside risk for cancer and accidental or violent demise. Gone was the French Paradox! The J curve is dead! Or not. Though that statement may be technically true, I looked at look at the data myself and found something different: a strong confirmation of the J-curve for overall mortality, overall cancer deaths, cardiovascular disease, and all “other causes.” This held for both men and women:
